Purpose
Credits
5
This unit standard is intended for use in the training and
assessment of process automation technicians in developing
techniques to analyse control requirements for automated
industrial process plant.
People credited with this unit standard are able to:
–
explain the purpose of user and functional specifications
for the defining of automated industrial processes; and
–
develop user and functional requirement specifications for
automated industrial processes.

Entry information
Recommended skills
and knowledge
It is expected that candidates for assessment against this unit
standard will already have achieved an electrical qualification
such as the National Certificate in Industrial Measurement and
Control (Level 4) [Ref: 0410], National Certificate in Electrical
Engineering (Electrician for Registration) (Level 4) [Ref: 1195],
New Zealand Diploma in Engineering [Ref: 112950], or
demonstrate equivalent or higher skills and knowledge.
Alternatively, candidates may have skills and knowledge
associated with mechanical installation and maintenance of
automated systems.

Definition
Industry practice – those practices that competent practitioners within the industry
recognise as current industry best practice.

The intention of this unit standard is not to produce programming software for
automated control of industrial processes but to develop the planning and design
skills required for technicians to produce structured function requirement
specifications for an industrial process.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMR). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
